This flexibility may beprovided by` 40 making the screen .loose .l or providing awtuckf.l

therein, or'by using a conventional type of collapsible screen. As a matter of fact, ascreen mounted inthe usual manner. is sufciently flexible toallow contraction of the frame l suiii- 45 ciently to allow insertion thereof in the window frame. e*

Canopy 3 extends beyond the top of frame I to which it is aixed, .this extension forming an apron 4 passing vbetween the top -of the frame 50 and thebottom sash of the window. This apron has lloops 5 attached to the edgethereof which p are fastened to window lifts 6, or' in case the Window has no lifts, to hooks vor the like, at-

, tached to the bottom of the window.v Thisapron 56 passing under the window will prevent the pene'- f tration of rain or wind, etc., through the crack between window and frame, and will also give the awning or canopy additional support.

In the installation of my Ventilator, a suitable size is selected, the window opened, the clamps II are unfastened, handle I2 is grasped with one hand, and the opposite side of the frame with the other,v and the dowels 8 areshoved into grooves!) Icompressing openings I4. The frame,

` while compressed, is inserted into the grooves of the window frame resting on the bottom I5 of said frame, and the handle I2 is released, expanding the springs Ill and securing the frame inthe z" Slots II are then slipped over the bolts j* holding wing nuts I0 which are then v-tightened making frame Irigid. The window 2 isthen closed on top of frame I with apron 4 on thel inside. Loops 5 are then attached to the window lifts IS, and if necessary the window may be raised slightly to make the apron taut. y

Ifthe Ventilator is to be placedin theztop `portion of the window frame, `theupper sash of the window may be lowered and the same procedure followed.` Inthis case, the 4use of the apron .4 rmay be dispensed with, or the loops thereof may be attached to the upper part of theframe.

. In the form of myinvention described in Figure 4, the installation is similar to that described .with respect Vto the modification shown in Figure 2,v the frame and canopy being *constructed in a similar manner. In this embodiment it is found desirable to mount the frame I in the lower portion of the vouter channel I9 in a window frame constructed with apair of vertical channelsin lwhichlthe upper *and lowerwindows ride,

lower window 2, which rides in inner channel 20;

is thenV raised so that its lower portion is o pposite the topof frame I, Vand the apron for canopy Vextension 4 is passed underneath the bottom 'por-I tion of the sash ofwindow 2 and the loops 5 or other attachment members are attached to the lifts 6 on the window sash, or to other fastening -meanson the window frame as described'wth reference to the modification shown in `Figure 2.. The advantage of this form of my inventionA resides in the fact that the ventilator may remain permanently inthe window frame since, when it is desired to close the lowerwindo'w, the loops on the apronmay bedetached fromthle fastening l means on the window frame. When this' is done,

thewindow may be lowered in its inner channel, andthe Ventilator remains in the outer channel ready for. use. x I

When it is desired to use the Ventilator of my invention in window frames which do not have channels of the type referred to, or whereit is not desired to mount the said ventilator in the y, channel, kmy ventilator may be fastenedvin the g V() window frame by other means, such as by means v amines lthereto and The zontal'members and endv members; eaehfoffl horizontal members comprising two separatepor of hooks or clampsthe frame" of the ventilator;

being mounted on the exterior of the window` frame. The lower ywindow is then ropened tothe appropriate height and the "canopy extension or apron may be passed under the windowI andl atl tached as'described above. When the extension is detached, the ventilator willy remain in kplacef for use, and the window may be raised in the usual manner.
